1 Ceres at perihelion

Objects: 1 Ceres

1 Ceres's 4.6-year orbit around the Sun will carry it to its closest point to the Sun – its perihelion – at a distance of 2.55 AU.

In practice, however, 1 Ceres's orbit is very close to circular; its distance from the Sun only varies by about 17.2% between perihelion and aphelion. This means that the difference in the amount of heat and light it receives from the Sun between aphelion and perihelion is extremely small.

Finding 1 Ceres

1 Ceres's distance from the Sun doesn't affect its appearance. From Fairfield, at the moment of perihelion it will be visible in the morning sky, becoming accessible around 19:33, when it reaches an altitude of 21° above your eastern horizon. It will then reach its highest point in the sky at 00:59, 73° above your southern horizon. It will be lost to dawn twilight around 05:36, 30° above your western horizon.

A chart of the path of 1 Ceres across the sky in 2032 can be found here, and a chart of its rising and setting times here.

The position of 1 Ceres at the moment it passes perihelion will be:
